The innovation in the baking process lowers the cost of producing pizzas. Therefore, for any given price of a pizza, sellers are willing and able to supply more pizzas. Visually, this is seen as a rightward shift of the supply curve.
Note that the demand curve does not shift, because none of the factors affecting demand have changed. In particular, the demand curve shifts in response to changes in any of the following:
• | Price of a related good (complement or substitute) |
• | Income of consumers |
• | Tastes of consumers |
• | Number of consumers |
• | Expectations of consumers |
